you can use json_decode php function : http://php.net/manual/fr/function.json-decode.php

on code :

    <?php      $host = 'https://apirest.3dcart.com';     $version = 1;     $service = 'orders';     $secureurl = 'https://xxxxyyyyy.3dcart.net';   // secure url set in settings->general->storesettings     $privatekey = 'xxxxxxxxxxxxxxxx'; // private key obtained when registering app @ http://devportal.3dcart.com     $token = 'xxxxxxxxxxxxx';      // token generated when customer authorizes app     // initialize curl session     $ch = curl_init($host . '/3dcartwebapi/v' . $version . '/' . $service);     // set headers     $httpheader = array(             'content-type: application/json;charset=utf-8',             'accept: application/json',             'secureurl: ' . $secureurl,             'privatekey: ' . $privatekey,             'token: ' . $token,     );     curl_setopt($ch, curlopt_httpheader, $httpheader);     // [ ... addtional curl options needed ... ]     $response = curl_exec($ch);        if ($response === false) {         $response = curl_error($ch);     }      curl_close($ch);  $arrayresponse = json_decode($response, true); //do array
